Written by Vena Angier, wife of Bradford Angier, it details their very first adventure in backwoods living. Both went on to be highly acclaimed wilderness writers. The descriptions of the canadian wilds and close community are wonderful. It was written in 1951 so she does have a bit of a 50's housewife tone in the beginning that can grate. But Vena's writing voice quickly becomes a pleasant mixture of sensitive appreciation for rustic life and intrepid adventure. If you're interested, it should be easy to find, I think there were quite a few printings
I have this in my library. As you note, its voice is certainly dated, to put it mildly. And yet they actually did it, so it's worth looking through. Only a fool dismisses hard experience -- there's always something useful to be gleaned.
